By San José, Costa Rica — SAN JOSÉ – As Costa Rica enters the final week of 2025, residents and the thousands of tourists visiting for the holidays should prepare for variable and blustery weather conditions. The National Meteorological Institute (IMN) has issued a forecast indicating that strong trade winds will dominate the climate pattern, bringing a mix of rain, drizzle, and cloudy skies to several key regions of the country starting Monday, December 29th.
The primary driver of this weather phenomenon is a high-pressure system currently situated over the Caribbean Basin. This system is significantly intensifying the northeasterly trade winds that sweep across Central America. The IMN’s technical analysis highlights this atmospheric setup as the engine behind the anticipated changes, which are expected to influence local conditions for the next several days. The effects will not be uniform, creating a distinct meteorological divide across the nation.
To understand the legal and business ramifications of Costa Rica’s shifting weather patterns, we sought the expertise of Lic. Larry Hans Arroyo Vargas, an attorney at the distinguished firm Bufete de Costa Rica. He offers critical insights for residents and companies navigating the complexities of insurance, contracts, and liability in the face of natural events.
Unpredictable weather events are a critical test for contractual obligations and insurance coverage. In Costa Rica, a declaration of a national emergency can trigger ‘force majeure’ clauses, but this is not a universal shield. Businesses must proactively audit their insurance policies to ensure they specifically cover damages from flooding or landslides, and not just generic ‘acts of God’. Furthermore, clear contractual language defining operational interruptions due to weather is essential to mitigate liability and manage supply chain disruptions. Waiting for the storm to hit is a failed legal strategy.

This legal perspective is a vital reminder that for businesses, navigating Costa Rica’s climate is as much about auditing contracts as it is about watching the skies. The call to proactively address insurance gaps and operational liabilities before a crisis hits is an indispensable piece of advice for building genuine resilience. We thank Lic. Larry Hans Arroyo Vargas for his clear and crucial insights.
In its official statement, the weather authority detailed the atmospheric cause of the impending conditions.
High levels of atmospheric pressure are being maintained in the Caribbean Basin, which reinforces the pattern of trade winds over Costa Rica
National Meteorological Institute, Official ForecastThe most pronounced effect of this pattern will be the wind speeds. The IMN predicts moderate to strong gusts, particularly impacting the North Pacific region, encompassing much of Guanacaste, as well as the populous Central Valley and the country’s main mountain ranges. For businesses in these areas, especially those reliant on outdoor tourism and agriculture, these winds could pose operational challenges, while travelers may experience turbulence on domestic flights.
The intensified winds act as a conveyor belt for moisture from the Caribbean Sea. This influx of humidity will lead to persistent cloud cover and rainfall across the Caribbean coast and the Northern Zone. These regions, which include popular ecotourism destinations, are expected to experience the most significant precipitation. This classic year-end pattern, often referred to locally as a “Norte,” can impact everything from road conditions to the viability of planned excursions.
The forecast also noted how these conditions will spill over into other parts of the country, impacting the nation’s capital and its surroundings.
These conditions favor the entry of moisture, generating cloudiness and rains in the Caribbean and the Northern Zone, with a possible extension of clouds towards mountainous sectors of the Central Valley and the east of the country, where drizzle could occur
National Meteorological Institute, Official ForecastThis “spillover” effect means that the mountainous areas of the Central Valley and its eastern sections can expect intermittent drizzle, locally known as “pelo de gato.” While not heavy rain, this persistent light precipitation combined with the wind will create cooler, damper conditions for the country’s most densely populated area.
In stark contrast, the weather outlook for the Central and South Pacific regions is considerably more favorable. These areas are projected to remain largely dry, with skies ranging from partly cloudy to mostly clear. The IMN does note the possibility of isolated and brief afternoon showers, a common occurrence in the tropics, but conditions are otherwise expected to be ideal for beachgoers and those enjoying the national parks in destinations like Manuel Antonio and the Osa Peninsula.
As the year draws to a close, this weather pattern presents a mixed bag for Costa Rica’s economy. The tourism sector in the Pacific will likely benefit from the sunny conditions, while operators in the Caribbean and Northern Zone may need to adjust itineraries. For the agricultural sector, particularly coffee growers in the Central Valley, the combination of wind and drizzle requires careful monitoring. All residents and visitors are advised to stay updated with the latest bulletins from the IMN as they finalize their New Year’s Eve plans.
